In this function, once 'buf' has been allocated, we unconditionally return 0. However, 'error' is set to some error codes in several error handling paths. Before commit232b51948b("xfs: simplify the xfs_getbmap interface") this was not an issue because all error paths were returning directly, but now that some cleanup at the end may be needed, we must propagate the error code.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
